Application led June 2S,

The present invention relates primarily to release mechanisms for wringer rolls. Among the objects of my invention are: to provide, in wringer, mechanism whereby the tension on the wringer rolls may be easily and quickly released in the event clothing should get hunched or the lingers caught ietween the rolls, or if for any other reason it should be desirable to release the tension; to provide mechanism ot' the character described such that the tension on the rolls can be easily released without the fingers lgetting injured; to provide release mechanism of the character stated, which is easily reset to normal operating position after it has been released; to improve in general upon mechanisms et the character' stated; and such turther objects, advantages and capabilities as will later more fully appear.

lily Vinvention further resides in the con bination, construction and rrangement oi' parts illustrated in the accompanying drawing, 'and while l have shown therein proferred embodiments l desire the same to be understood as illustrative only and not as limiting my invention, Y

ln the drawing annexed hereto and forming a part hereof, Fig. 1 is a sectional elevation et a wringer embodying my improvements; 2 is atransverse section substantially along the plane indicated by the line 22 Fig. 1; and Fig. 3 is a fragmentary section oi" a modification orn my release mecha nism. Y

1ieieerring more in detail' to the drawing, numeral 1 denotes the upright side members or" the wringer frame, 2 the wringer rolls and 3 the gear casings surrounding the gears and the ends of the rolls as is customary. Connecting the members 1 are cross bars or plates 4, provided centrally with hollow bosses 5, in the hollows 6 of which slide the trunnions 7 on 'block 8. rEhe block 8 is provided as shown with a notch 9, adapted to engage an abutment member, such as a bolt 10 passing through and connecting the side plates 4, which are also connected by means of a plurality ot bolts 11. Passing approximately centrally through block 8 is a screw threaded tension adjusting means 12 provided with a hand wheel 13. rlhis rests at its lower end upon a spring 14 which serves to transmit tension to the rollers 2 so as to hold them yieldingly, as is customary. lt will be seen from the above that when the parts are in the solid line position, shown 1921'. serial No. 440,'6524.

in Figs. 1 and 8, there will be a direct 4ulpward thrust of the spr-ing 14 against the 'end of screw 12, which is transmitted thereby lto the bloclr S, which lis prevented trom upward movement by `the bolt 10 engaging in notch 9. Then it is desired to release the tension on spr-ing 14 and the rollers 2, it is only necessary to press downwardly' on' handle 15 connected with block 8 and notch Suis moved out of 'engagement with 'bolt 10, thereby releasing block 8 for movement upwardly. When this happens trunnions 7 slide upwardly in the grooves 6 and so quickly release the pressure on the rolls. Inbrder to reduce wear and render the devi-ce more easy oi' operation, bolt 10 isv surrounded by a sleeve which is, -in elifect, a roller bearing, the trunnions 7 and tops of grooves 6 co-operating to permit bodily movement ot block 8 but preventing same from becoming detached;

In the form shown in Fie'. 3 it might be possible for one to get the fingers between the handle 15 and the side pieces 4 and thereby get hurt when the tension is released from the rollers. In the form shown in Fig.

16 in the handle 15 so thatfwhen the handle is pressed downwardly the block 8 can be released from bolt 1-0 as described, but the further movement of this block under the influence of'spring 14 cannot cause the end of handle 15 to pinch the lingers between the handle and the side plates 4.

' 1 this danger is obviated by placing a hinge It will be seen from theabove'that with 1 my new construction it' will be extremely simple t0 press the handle 175 downwardly as indicate-d and release the tension 0n the rolls 2 and thatv when so released the upper roll can move upwardly a considerable distance so that bunches of clothing going through the wringer rolls will not cause any damage. It is also clear that rit is easy to return the parts to normal rposition after the clothing or other obstruction 'hasbe'en removed. from the wringer. It is further clear that with the construction shown in Fig. 1 it will be impossible to get the hands hurt between the handle 15 and side pieces 4. Along with these advantages is the advantage ot being able to have a uniform tension on the two ends of the rolls because of the fact that the tension is transmitted froml description ot structure set forth above may be departed from without departing troni the spirit of my invention.

Having now described myinvention l claim:

l. In a wringer, a pair of rolls, a spring for placing tension upon said rolls, said wringer having a pair o1 side members provided with approximately centrally arranged grooves, a block between said side members carrying a pair ot' trunnions, said trunnions being slidable in the grooves in the side plates, said block carrying tension adjusting means adapted to engage the spring and transmit tension therethrough to the wringer rolls, said block being provided with a notch and said plates being connected by a bolt adapted to engage in said notch to hold the block in normal position, and a handle for tilting said block on its trunnions to release the notch from the bolt, thereby releasing the tension on the wringer rolls.

2. In a wringer having a pair ot spaced side members and a roll tensioning spring, means extending transversely,between and connected to said side members and adapted to serve as an abutment tor a movable member, avmovable member in engagement with said spring, side members and abutment means adapted to hold the spring under tension, and means for moving the spring holding means out of engagement with the abutment so that it may move bodily away from the rolls to permit. quick release ont the tension on the spring.

3. ln a wringer7 a. trame having an opening and having` an abutmentwithin its opening, a block pivotally mounted within said opening and capable oi"- sliding movement therein in a direction transverse to the pivotal axis, said block being adapted in one position thereo'l to engage said abut" ment so as to be prevented from sliding movement and, further, being adapted to be readily moved pivotally to be released from said abutment.

4. In a wringer, a frame having an opening and having an abutment within its opening, a block pivotally mounted within said opening and capable ot sliding movement therein in a direction transverse to the pivotal axis, said block being adapted inone position thereof to engage said abutment so reoreea as to be prevented from sliding movement and, further, being adapted to be readily moved pivotally to be released trom said abutment, and means rigid with said block tor manually moving said block on its pivots.

5. ln a wringer, a frame having an openingand havingvan abutment within its opening, block pivotally mounted within said opening and capable of sliding movement therein, said block being adapted in one position thereot to engage said abu Vment so as to be prevented from sliding movement and, further, being adapted to be readily moved pivotally to be released from said abutment, and a handle comprising sections jointed together to break upwardly when the handle moved toward the trame when manually releasing said block 'from the abutment.

G. ln a wringer comprising a trame carrying rolls and compressing means therefor, the combination et means for varying the compression ot the rolls, means normally holding the varying means in compressing position, and a handle formed of jointed sections adapted to break upwardly when moved towards the trame to release the varying means.

'r'. ln a wringer, a trame having an opening and having an abutment and guideways within its opening, a block mounted within said opening on pivots capable of sliding movement in said guideways, said blocl having means adapted, in one position thereogt, to engage said abutment so as to be prevented from sliding movement and, further,

being adapted to be readily moved pivotally to be released from said abutment, said abutment comprising a rotatably mounted sleeve.

8. ln a wringer having a trame comprising si le members so positioned as to torm an open top, an abutment within said. top comprising a rotatably mounted sleeve, supported by the side members, a movable meniber in said top adapted to rest against said abutment and to be detached therefrom. means permitting said member bodily and pivotally but preventing aine from becoming detached from the tvo-p.

ln witness whereof, l hereunto subscribe my name to this speciiicat-ion.
